httpd 2.4.2 + mysql-5.5.24 + php-5.4.4編譯安裝過程：
一、編譯安裝apache
1、httpd-2.4.2需要較新版本的apr和apr-util，是以需要事先對其進行更新,另外，httpd-2.4.2編譯過程也要依賴于pcre-devel軟體包，需要事先安裝。
# yum -y install pcre-devel
# tar xf apr-1.4.6.tar.bz2
# ./configure --prefix=/usr/local/apr
# make
# make install
tar xf apr-util-1.4.1.tar.bz2
# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
2、安裝http
# tar xf httpd-2.4.2.tar.bz2
# cd httpd-2.4.2
# ./configure --prefix=/usr/local/apache --sysconfdir=/etc/httpd --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
# make && make install
3、修改httpd的主配置檔案，設定其Pid檔案的路徑
編輯/etc/httpd/httpd.conf，添加如下行即可：
PidFile "/var/run/httpd.pid"
4、提供啟動服務腳本/etc/rc.d/init.d/httpd，從别的機器copy的httpd啟動腳本，稍作修改即可内容如下：
#!/bin/bash
#
# httpd Startup script for the Apache HTTP Server
# chkconfig: - 85 15
# description: Apache is a World Wide Web server. It is used to serve \
# HTML files and CGI.
# processname: httpd
# config: /etc/httpd/conf/httpd.conf
# config: /etc/sysconfig/httpd
# pidfile: /var/run/httpd.pid
# Source function library.
. /etc/rc.d/init.d/functions
if [ -f /etc/sysconfig/httpd ]; then
. /etc/sysconfig/httpd
fi
# Start httpd in the C locale by default.
HTTPD_LANG=${HTTPD_LANG-"C"}
# This will prevent initlog from swallowing up a pass-phrase prompt if
# mod_ssl needs a pass-phrase from the user.
INITLOG_ARGS=""
# Set HTTPD=/usr/sbin/httpd.worker in /etc/sysconfig/httpd to use a server
# with the thread-based "worker" MPM; BE WARNED that some modules may not
# work correctly with a thread-based MPM; notably PHP will refuse to start.
# Path to the apachectl script, server binary, and short-form for messages.
apachectl=/usr/local/apache/bin/apachectl
httpd=${HTTPD-/usr/local/apache/bin/httpd}
prog=httpd
pidfile=${PIDFILE-/var/run/httpd.pid}
lockfile=${LOCKFILE-/var/lock/subsys/httpd}
RETVAL=0
start() {
echo -n $"Starting $prog: "
LANG=$HTTPD_LANG daemon --pidfile=${pidfile} $httpd $OPTIONS
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch ${lockfile}
return $RETVAL
}
stop() {
echo -n $"Stopping $prog: "
killproc -p ${pidfile} -d 10 $httpd
[ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}
reload() {
echo -n $"Reloading $prog: "
if ! LANG=$HTTPD_LANG $httpd $OPTIONS -t >&/dev/null; then
echo $"not reloading due to configuration syntax error"
failure $"not reloading $httpd due to configuration syntax error"
else
killproc -p ${pidfile} $httpd -HUP
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
status)
status -p ${pidfile} $httpd
restart)
condrestart)
if [ -f ${pidfile} ] ; then
reload)
reload
graceful|help|configtest|fullstatus)
$apachectl $@
*)
echo $"Usage: $prog {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}"
exit 1
esac
exit $RETVAL
而後為此腳本賦予執行權限：
# chmod +x /etc/rc.d/init.d/httpd
加入服務清單：
# chkconfig --add httpd
設定PATH，省的老用絕對路徑，永久生效的話寫在/etc/profile/裡export前面即可
# export PATH=/usr/local/apache/bin/:$PATH
接下來就可以啟動服務進行測試了。
二、安裝mysql-5.5.24
1、建立使用者資訊，和資料存放位置
# groupadd -r mysql
# useradd -g mysql -r -s /sbin/nologin -M -d /mydata/data mysql
# mkdir -p /mydata/data
# chown -R mysql.mysql /mydata/data/
因為Mysql比較大，，是以這裡用的是綠色安裝的軟體解壓即可使用
# tar xf mysql-5.5.24-linux2.6-i686.tar.gz -C /usr/local/
# cd /usr/local/
# ln -s mysql-5.5.24-linux2.6-i686/ mysql
# cd mysql
# chown -R mysql.mysql .
# scripts/mysql_install_db --user=mysql --datadir=/mydata/data
# chown -R root .
2、為mysql提供主配置檔案：
# cd /usr/local/mysql
# cp support-files/my-large.cnf /etc/my.cnf
并修改此檔案中thread_concurrency的值為你的CPU個數乘以2，比如這裡使用如下行：
thread_concurrency = 2
另外還需要添加如下行指定mysql資料檔案的存放位置：
datadir = /mydata/data
3、為mysql提供服務啟動腳本：
# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
添加至服務清單：
# chkconfig --add mysqld
# chkconfig mysqld on
修改PATH環境變量，讓系統可以直接使用mysql的相關指令。重新開機生效的話一樣寫在/etc/profile
# export PATH=/usr/local/mysql/bin:$PATH
三、編譯安裝php-5.4.4
1、需要依賴關系
# yum -y groupinstall "X Software Development"
如果想讓編譯的php支援mcrypt擴充，此處還需要下載下傳安裝如下軟體包
libmcrypt-2.5.7-5.el5.i386.rpm
libmcrypt-devel-2.5.7-5.el5.i386.rpm
2、編譯安裝php-5.4.4.
# tar xf php-5.4.4.tar.bz2
# cd php-5.4.4
# ./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --with-apxs2=/usr/local/apache/bin/apxs --with-mcrypt --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-bz2
3、為php提供配置檔案：
# cp php.ini-production /etc/php.ini
4、編輯apache配置檔案httpd.conf，以apache支援php
# vim /etc/httpd/httpd.conf
1)添加以下兩行
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
2)将DirectoryIndex index.html
修改為：
DirectoryIndex index.php index.html
5、重新啟動httpd，發現有錯誤。這是因為SElinux的原因，關閉會就Ok了
service httpd restart
Stopping httpd: [ OK ]
Starting httpd: httpd: Syntax error on line 148 of /etc/httpd/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied
[FAILED]
6、這裡寫個.php頁面做下測試
# cd /usr/local/apache/htdocs/
# cat index.php
<?php
phpinfo();
?>
下面在測試下與mysql的連接配接
$link=mysql_connect('localhost','root','');
if ($link)
echo "Sucess!!";
echo "Failuser!!";
mysql_close();
OK，成功了
三，安裝phpMyAdmin
# tar xf phpMyAdmin-3.5.1-all-languages.tar.bz2 -C /usr/local/apache/htdocs/
# mv phpMyAdmin-3.5.1-all-languages/ phpmyadmin
# service httpd restart
首先需要給資料庫設定密碼
mysql> SET PASSWORD FOR root@'localhost'=PASSWORD('redhat');
Query OK, 0 rows affected (0.09 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.04 sec)
# mv config.sample.inc.php config.inc.php
# vim config.inc.php 在a8b這裡随便添加字元即可
$cfg['blowfish_secret'] = 'a8b7cfdafs6d'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
下面通路下http://192.168.80.139/phpmyadmin
用apache自帶的ab來做下壓力測試，模拟下1000請求，100個并發
# ab -n 1000 -c 100 http://192.168.80.139/phpmyadmin/
在進行測試的時候通路發現已經通路很慢了，看下結果
Concurrency Level: 100 并發連接配接數
Time taken for tests: 39.878 seconds 測試過程消耗時間
Complete requests: 1000 總共完成的請求數
Failed requests: 0 失敗的請求數
Write errors: 0
Total transferred: 7502552 bytes 測試過程網絡傳輸量
HTML transferred: 6784000 bytes HTML記憶體傳輸量
Requests per second: 25.08 [#/sec] (mean) 平均每秒響應的請求數
Time per request: 3987.764 [ms] (mean) 平均每請求的響應時間
四
、安裝Discuz論壇
# unzip Discuz_7.2_FULL_SC_UTF8.zip -d /usr/local/apache/htdocs/
# vim /etc/php.ini
# short_open_tag = On
# cd /usr/local/apache/htdocs/upload/
# chown -R daemon config.inc.php p_w_uploads/ forumdata/ uc_client/data/cache/
下面通路http://192.168.80.139/upload/install 按步驟安裝即可
五
、安裝xcache-2.0.0
# tar xf xcache-2.0.0.tar.bz2
# cd xcache-2.0.0
# /usr/local/php/bin/phpize
# ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config
# make && make install
結束後會輸出一段話，如下
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20100525/
将xcache提供的樣例導入到php.ini中
mkdir /etc/php.d
cp xcache.ini /etc/php.d
# cat xcache.ini >> /etc/php.ini
添加，make install後輸出的一段話下的xcache.so
# vim /etc/php.d/xcache.ini
zend_extension = /usr/local/php/lib/php/extensions/no-debug-zts-20100525/xcache.so
# service httpd restart
通過之前的index.php可以檢視到這裡已經有xcache的支援了
之後我們在重新做下ab壓力測試，對比一下之前的看看，這裡就不介紹了。
